	Presidential Commission Report on the Challenger Accident (Site not responding. Last check: 2007-09-12)
		NASA did not accept the judgment of its engineers that the design was unacceptable, and as the joint problems grew in number and severity NASA minimized them in management briefings and reports.
		NASA has initiated efforts to examine other launch vehicle alternatives for the major NASA planetary and scientific payloads which were scheduled to utilize the Centaur upper stage.
		NASA is providing assistance to the Department of Defense as it examines alternatives for those national security missions which had planned to use the Shuttle/Centaur.

	Spaceflight Now \| STS-107 Mission Report
		NASA is considering five options for redesigning the so-called "bi-pod" ramp system on the shuttle's external fuel tank, the area where a chunk of foam insulation broke away during Columbia's launch, hit the left wing and possibly caused a catastrophic breach.
		A NASA flight director told the Columbia Accident Investigation Board Monday he was amazed the doomed spacecraft was able to continue flying in relatively normal fashion for nearly 10 minutes while shedding multiple pieces of flaming debris as a plume of superheated air burned its way into the stricken ship's left wing.
		NASA managers say an engineer's email discussing a worst-case scenario based on the assumption a foam debris impact during the shuttle Columbia's launch did, in fact, seriously damage the ship's heat-shield tiles is an example of normal "what-ifing" and not an expression of real concern that somehow failed to reach upper management.

	NASA FACTS, UFO Casebook
		NASA was formed in 1958 and from the very start a number of it's astronauts and test pilots testified to sighting UFOs or craft of undetermined origin.
		NASA refused to reveal any evidence that might substantiate the pilots' claims -- photographs or films were never released.
		The FBI files infer that NASA was (is) withholding filmed evidence of UFOs to which the general public is being denied access and the remarks about Gemini 4 is of special interest because James McDivitt, a pilot with Gemini 4, confirmed that during the mission he did see an "unidentified object".

	CBS News Coverage of Shuttle Mission STS-114
		NASA managers are hopeful whatever caused the foam to separate will be traced to an isolated problem with tank No. 121 and not a generic issue requiring a fleet-wide redesign.
		NASA officials said today that foam in the area that pulled away was slightly damaged during the tank's processing, requiring a standard repair for relatively routine cracks and gouges.
		NASA status reports can be found on the shuttle/station web page or the Kennedy Space Center's pre-launch status report archive.

		One of the interesting facts about the historical development of rockets is that while rockets and rocket-powered devices have been in use for more than two thousand years, it has been only in the last three hundred years that rocket experimenters have had a scientific basis for understanding how they work.
		This law of motion is just an obvious statement of fact, but to know what it means, it is necessary to understand the terms rest, motion, and unbalanced force.
		While sitting "still," you are, in fact, traveling at a speed of hundreds of kilometers per second.
